Your best friend’s grandmother has just suffered a stroke. This stroke has left her with an inability to speak, but she can stil
l understand what others say to her. She also has paralysis on the right side of her body. Your friend wants to know what part of her grandmother’s brain was likely damaged by the stroke. Based on your understanding of the brain, what would you tell your friend?
The reason behind a stroke includes- blockage in supply of blood into the brain or blasting of a brain blood vessel. It may result to Paralysis of either parts of the body or any one side of it.
A right-side paralysis of body and inability to speak can be a symptom of Paresis or right-side paralysis. Paresis occurs due to damage in the left-hemisphere or lefty-portion of brain, as the left brain controls the ride side of our body. So, I will tell about the left brain damage of her grandmother.
The stroke would have happened on the left side of her body. The left cerebrum controls speaking, so it would make sense that her speech was slow and/or slurred. The right side of the body is controlled by the left brain, so the right side would become paralyzed. The right side of the cerebrum has to do with emotions, so being able to understand what people say is a sign of a stroke on the left side of the brain.
I would explain to her that most likely the teeth will not repair themselves due to the fact that, unlike bone, enamel does not contain cells that are capable of remodeling and repair. However, some remineralization is possible.
